	---help---

	  b43 is a driver for the Broadcom 43xx series wireless devices.



	  Check "lspci" for something like

	  "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"

	  to determine whether you own such a device.



	  This driver supports the new BCM43xx IEEE 802.11G devices, but not

	  the old IEEE 802.11B devices. Old devices are supported by

	  the b43legacy driver.

	  Note that this has nothing to do with the standard that your AccessPoint

	  supports (A, B, G or a combination).

	  IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.



	  It is safe to include both b43 and b43legacy as the underlying glue

	  layer will automatically load the correct version for your device.



	  This driver uses V4 firmware, which must be installed separately using

	  b43-fwcutter.



	  This driver can be built as a module (recommended) that will be called "b43".

	  If unsure, say M.



# Auto-select SSB PCI-HOST support, if possible

config B43_PCI_AUTOSELECT

	bool

	depends on B43 && SSB_PCIHOST_POSSIBLE

	select SSB_PCIHOST

	default y



# Auto-select SSB PCICORE driver, if possible

config B43_PCICORE_AUTOSELECT

	bool

	depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE

	select SSB_DRIVER_PCICORE

	default y



config B43_PCMCIA

	bool "Broadcom 43xx PCMCIA device support (EXPERIMENTAL)"

	depends on B43 && SSB_PCMCIAHOST_POSSIBLE && EXPERIMENTAL

	select SSB_PCMCIAHOST

	---help---

	  Broadcom 43xx PCMCIA device support.



	  Support for 16bit PCMCIA devices.

	  Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA

	  devices, but 32bit CardBUS devices. CardBUS devices are supported

	  out of the box by b43.



	  With this config option you can drive b43 cards in

	  CompactFlash formfactor in a PCMCIA adaptor.

	  CF b43 cards can sometimes be found in handheld PCs.



	  It's safe to select Y here, even if you don't have a B43 PCMCIA device.



	  If unsure, say N.



config B43_DEBUG

	bool "Broadcom 43xx debugging"

	depends on B43

	---help---

	  Broadcom 43xx debugging messages.



	  Say Y, if you want to find out why the driver does not

	  work for you.



config B43_DMA

	bool

	depends on B43

config B43_PIO

	bool

	depends on B43



choice

	prompt "Broadcom 43xx data transfer mode"

	depends on B43

	default B43_DMA_AND_PIO_MODE



config B43_DMA_AND_PIO_MODE

	bool "DMA + PIO"

	select B43_DMA

	select B43_PIO

	---help---

	  Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)

	  data transfer modes.

	  The actually used mode is selectable through the module

	  parameter "pio". If the module parameter is pio=0, DMA is used.

	  Otherwise PIO is used. DMA is default.



	  If unsure, choose this option.



config B43_DMA_MODE

	bool "DMA (Direct Memory Access) only"

	select B43_DMA

	---help---

	  Only include Direct Memory Access (DMA).

	  This reduces the size of the driver module, by omitting the PIO code.



config B43_PIO_MODE

	bool "PIO (Programmed I/O) only"

	select B43_PIO

	---help---

	  Only include Programmed I/O (PIO).

	  This reduces the size of the driver module, by omitting the DMA code.

	  Please note that PIO transfers are slow (compared to DMA).



	  Also note that not all devices of the 43xx series support PIO.

	  The 4306 (Apple Airport Extreme and others) supports PIO, while

	  the 4318 is known to _not_ support PIO.



	  Only use PIO, if DMA does not work for you.
